NYSTCE ATAS Mathematical Concepts and Operations 4

Question 1

A student solves 56 ÷ 8 and gets 6. How can a teaching assistant best help the student check this answer?

Accepted Answer

Have the student multiply 6 × 8 to see if it equals 56

Answer

Multiplication is the inverse of division, so checking 6 × 8 = 48 ≠ 56 reveals the error.

Question 2

What is the perimeter of a square with a side length of 7 inches?

Accepted Answer

28 inches

Answer

Perimeter of a square = 4 × side = 4 × 7 = 28 inches.

Question 3

Which of the following numbers is divisible by both 3 and 4?

Accepted Answer

24

Answer

24 ÷ 3 = 8 and 24 ÷ 4 = 6, so 24 is divisible by both 3 and 4.

Question 4

A recipe calls for 2¼ cups of flour. A student wants to make half the recipe. How much flour is needed?

Accepted Answer

1⅛ cups

Answer

2¼ = 9/4; half of 9/4 = 9/8 = 1⅛ cups.

Question 5

A student plots the point (−2, 3) on a coordinate grid. In which quadrant is this point located?

Accepted Answer

Quadrant II

Answer

Quadrant II contains points where x is negative and y is positive, which matches (−2, 3).
